Value Collection ZBD9500-206 Viton O-ring Dash 206

Product Description

The VALUE COLLECTION ZBD9500-206 is a Dash 206 Viton O-ring designed for static and dynamic sealing applications in fluid and gas systems. With a 0.500-inch inside diameter, 0.750-inch outside diameter, and 0.125-inch cross-section thickness, this O-ring follows standard AS568 Dash 206 dimensions. The fluoroelastomer (Viton) compound provides strong resistance to fuels, oils, hydraulic fluids, and a wide range of chemicals. It carries a hardness rating of 75 Shore A, classifying it as hard, which supports reliable sealing under pressure. Plumbers, HVAC technicians, and industrial service professionals regularly use this size in valve assemblies, fittings, and pump seals.

This O-ring suits residential and light commercial plumbing, HVAC refrigerant-side connections, and industrial fluid-handling equipment where elevated temperatures or chemical exposure rules out standard Buna-N or EPDM compounds. The Viton material handles service temperatures from -15 degrees F to 400 degrees F, making it appropriate for hot water systems, fuel lines, and solvent-exposed assemblies. The round cross-section profile seats cleanly in standard O-ring grooves machined to Dash 206 specifications. Sold individually with a minimum order quantity of 25 units.

Key Features

• 75 Shore A hardness rating provides firm, reliable groove seating
• Rated for continuous service from -15 degrees F to 400 degrees F
• Round cross-section profile for consistent compression and seal integrity
• Lightweight at 0.01 pounds per unit for easy field stocking

Compatibility

Designed as a direct-fit replacement or service seal for any application requiring a standard Dash 206 O-ring groove with a 0.500-inch inside diameter and 0.125-inch cross section.

Installation Notes

O-ring installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Always depressurize and de-energize the system and isolate fluid supply before removing old seals. Lubricate the O-ring with a compatible grease or lubricant rated for use with Viton compounds before seating — petroleum-based lubricants may degrade fluoroelastomer over time. Inspect the groove for burrs or damage before installation to avoid seal failure.
